Ground Fault Locator PITE 3836

Project Description

Cost can be tremendous upon bad insulation or grounding in the power system. It may even cause power break-off which is costly to repair. Therefore, fast localization and elimination of grounding faults will be significant for electricians and technicians. It is also required by DIN VDE 0100-410 (VDE 0100-410): 2007-06 chapter 411.6.3.1 and IEC 60364-4-41 chapter 413.1.5.4. PITE 3836 is developed to fast detect, track and locate virtual grounding faults on DC systems. This spares you from hours of unnecessary troubleshooting and helps to increase the reliability of your electrical equipment. It is widely used in locomotive, telecom, power utilities, etc

PITE 3836 uses comprehensive ways to pinpoint the faults with the following working rules:

Signal generator has two testing leads connected with DC system. And it injects a low-frequency current signal with direction to the DC system. This signal will flow from testing lead to circuit, outflow from the faulty grounding point and finally flow back to the signal generator. This makes a return circuit that will be useful for signal tracing in the next step.

Signal receiver will trace this current signal with the help of current direction judgment. Direction of current signal always goes to the faulty point. With one clamp on two busbars or two clamps respectively on two busbars, it could work effectively with strong anti-interference when system is online.

Strength and phase angle of current signal will have big changes before and after the grounding fault. They also help pinpoint the fault.
